Which exact filter construction has the reported MERV 15A and ISO ePM1 rating?

Both ratings are held on pocket filters made by VOLZ Filters, one of the manufacturing partners named on the company's About page, and not on a flat panel filter.

Eurovent Certita Certification certifies a ten-pocket filter at ISO ePM1 70% under ISO 16890, with an A class energy rating, on Certificate No. 15.06.011, and that class belongs to the filter tested and does not carry over to a panel filter. MERV 15A is recorded under ASHRAE 52.2-2017 with Appendix J in LMS Technologies, Report 6847, 5 November 2024, on a 24 × 24 × 30 in. pocket filter. LMS Technologies, Report LMS#9904, 28 April 2025, is a single-pass fractional efficiency test on a 24 × 24 × 2 in. pleated air filter in an ASHRAE 52.2 test duct, in accordance with standard LMS aerosol test procedures, and it is not the report that records MERV 15A. As the company's Validation page puts it, industry standards ASHRAE 52.2 Appendix J and ISO 16890 test electrostatic filters after their temporary charge is removed, showing how they perform without it. A rating belongs to the construction that was tested and to the conditions in the report, and neither rating carries over to a panel filter, to another size or to another product. Certificate No. 15.06.011 can be looked up at source in the Eurovent Certita Certification certified product directory.

All questions

Which certificates are current for the particular product being offered?

A certificate is the issuer's document, and whether it is current is shown by the issuer's own record.

The issuer's record is the authority on the current status of its own certificate, and both issuers publish one. OEKO-TEX publishes a public label check, in its own words: “Want to check if an OEKO-TEX® label is official? Simply enter the label number below.” The number to enter is 17.0.25812. Eurovent Certita Certification publishes a certified product directory of the products certified under its programmes, where Certificate No. 15.06.011 and the model it covers can be looked up. Certificate No. 15.06.011 covers a ten-pocket bag filter, not a flat panel filter; a rating belongs to the construction that was tested. The company names each certificate by its issuer and its number so that the check can be made at source. Each issuer's own record names the holder of its certificate. The company does not keep a separate register of certificate status, and does not publish one.

All questions

What certificate, if any, covers this exact product, manufacturing site and current production period?

The company has not published a certificate that names one product, one manufacturing site and one production period together.

What it does publish is each certificate and each report by its issuer and its number, so that the scope on the document itself can be read. Each document states its own scope, and that is the limit of what it covers. Eurovent Certita Certification Certificate No. 15.06.011 names the participant and the certified model. OEKO-TEX® STANDARD 100 certificate 17.0.25812 names its own holder, class and period. The Intertek and RST reports name the article tested and the date it was tested. The issuer's record states the current status. A request for the document behind a particular product can be made through the contact route at [email protected]. Both numbers can be checked at source: certificate 17.0.25812 in OEKO-TEX’s public label check, and Certificate No. 15.06.011 in the Eurovent Certita Certification certified product directory. Certificate No. 15.06.011 covers a ten-pocket bag filter, not a flat panel filter; a rating belongs to the construction that was tested.

All questions

Is the cited document a test report, certification, accreditation record or company declaration?

They are four different kinds of document, and the company names each one for what it is.

The LMS Technologies, Intertek and RST Rail System Testing documents are test reports. Eurovent Certita Certification Certificate No. 15.06.011 and OEKO-TEX® STANDARD 100 certificate 17.0.25812 are certificates, issued by a certification body to a holder. A laboratory's ISO/IEC 17025 accreditation is an accreditation record, and it is about the laboratory. The company's Statement of Classification is a company declaration, issued by NF Technical Products Inc. The company names the laboratory for each report it cites, with the report number and the standard where the report prints them. A test report is not a certification, and an accreditation of a laboratory is not a statement about any product it tested. Both numbers can be checked at source: certificate 17.0.25812 in OEKO-TEX’s public label check, and Certificate No. 15.06.011 in the Eurovent Certita Certification certified product directory.

All questions

Are operating conditions outside the standard's stated scope being presented as if the result covers them?

No: each numbered report the company cites is named with its institution and number, and the company's own label sets the operating conditions for the filter.

A test result describes the article tested, at the conditions in the report. The label sets out the operating conditions in its own words: use in dry air only; do not use in ducts carrying liquid water, steam or oil mist, or anywhere the media may become wet; use in systems that run at or below the rated airflow and maximum face velocity; and air that passes around a filter is not treated by it. The label also states that results in a building depend on the system, the airflow, and how well the filter fits its track. The Terms of Use state: “A reported result describes only what the identified test found.”

All questions

Is the company authorized to display each certification mark in the manner and context shown?

The company names certificates by their issuer and their number, and it does not present a certification mark as its own.

The right to use a certification mark belongs to the holder of the certificate, under the issuer's rules. The certificates the company names are held by the manufacturer that makes the filters, not by C-POLAR: OEKO-TEX® STANDARD 100 certificate 17.0.25812, issued by OEKO-TEX Service GmbH, and Eurovent Certita Certification Certificate No. 15.06.011. Each issuer's own record names the holder of its certificate. Every commercial NanoFlashing™ product is made by a manufacturing partner, in that partner's facility and in that partner's format, and each partner controls what is said about the work. Both numbers can be checked at source: certificate 17.0.25812 in OEKO-TEX’s public label check, and Certificate No. 15.06.011 in the Eurovent Certita Certification certified product directory.

What product or manufacturing changes require review before the certificate or mark continues to be used?

The issuer decides that, and it decides it in the rules of its own scheme.

The issuer sets those conditions in its scheme rules, and they bind the holder of the certificate. The certificates the company names are held by the manufacturer that makes the filters. The company does not operate those schemes, does not set their thresholds, and does not publish a second set of rules alongside them. A certificate covers the product it names; a product that is no longer that product is a matter for the issuer.

Can every claimed local listing or certification be checked against the issuing authority's current record for the exact product and holder?

The two certificates the company names can each be checked against the issuer's own current record, by anyone.

The issuer's record is the authority on the current status of its own certificate, and both issuers publish one. OEKO-TEX publishes a public label check, in its own words: “Want to check if an OEKO-TEX® label is official? Simply enter the label number below.” The number to enter is 17.0.25812. Eurovent Certita Certification publishes a certified product directory of the products certified under its programmes, where Certificate No. 15.06.011 and the model it covers can be looked up. Certificate No. 15.06.011 covers a ten-pocket bag filter, not a flat panel filter; a rating belongs to the construction that was tested. The company names each certificate by its issuer and its number so that the check can be made at source. The other documents the company names are test reports rather than listings: LMS Technologies, Intertek and RST Rail System Testing reports are checked by reading the report itself or by asking the laboratory that issued it. The company does not keep a separate register of certificate status, and does not publish one.

Does the certification holder have permission to add an OEM's brand name?

That permission is the issuer's to give and the holder's to hold, and C-POLAR holds neither certificate.

The company names certificates by their issuer and their number, and it does not present a certification mark as its own. The certificates the company names are held by the manufacturer that makes the filters, not by C-POLAR: OEKO-TEX® STANDARD 100 certificate 17.0.25812, issued by OEKO-TEX Service GmbH, and Eurovent Certita Certification Certificate No. 15.06.011.

All questions

Does the certificate cover private-label variants listed under different model numbers?

A certificate covers the model it names, and nothing it does not name.

Both ratings are held on pocket filters made by VOLZ Filters, one of the manufacturing partners named on the company's About page, and a rating belongs to the construction that was tested and to the conditions in the report. Eurovent Certita Certification Certificate No. 15.06.011 names its participant and the certified model, and that model can be found in the issuer's public certified product directory. A model the certificate does not name is not covered by it, whoever sells it and whatever it is called. The company does not publish a list of private-label names, and a name it has not published is a question for whoever sells under it.

All questions

Would moving production to a new line at the same site require notification to the certifier?

The issuer decides that, and it decides it in the rules of its own scheme.

The issuer sets those conditions in its scheme rules, and they bind the holder of the certificate. The certificates the company names are held by the manufacturer that makes the filters. The company does not operate those schemes, does not set their thresholds, and does not publish a second set of rules alongside them. Eurovent Certita Certification publishes the rules of the programme under which Certificate No. 15.06.011 was issued, and OEKO-TEX Service GmbH publishes the rules of the scheme under which certificate 17.0.25812 was granted. Both numbers can be checked at source: certificate 17.0.25812 in OEKO-TEX’s public label check, and Certificate No. 15.06.011 in the Eurovent Certita Certification certified product directory.

All questions

Does the mark on the packaging correspond to the product or only to its power supply?

The NanoFlashing™ Air Filter is passive, so nothing on it could belong to a power supply.

The filter draws no power, and it has no power supply, electrode, lamp or reservoir. In use, the ventilation system's own fan moves air through it. The filter's label carries the product name, the size and weight fields, the rated airflow and maximum face velocity, the directions for use, the storage and disposal wording and the caution; it carries no certification mark. The company names certificates by their issuer and their number, and it does not present a certification mark as its own. The certificates the company names are OEKO-TEX® STANDARD 100 certificate 17.0.25812, issued by OEKO-TEX Service GmbH, and Eurovent Certita Certification Certificate No. 15.06.011, and each issuer's own record names the holder of its certificate. Where a partner builds the filter into an appliance, that appliance is a different product, and its marks and its power supply are the partner's. Both numbers can be checked at source: certificate 17.0.25812 in OEKO-TEX’s public label check, and Certificate No. 15.06.011 in the Eurovent Certita Certification certified product directory.

All questions

Can a laboratory accreditation symbol appear on a product label under the issuer's rules?

An accreditation is about a laboratory, not about a product, and the filter's label carries no accreditation symbol.

A laboratory's ISO/IEC 17025 accreditation is an accreditation record, and it is about the laboratory. It belongs to the laboratory and to the reports that laboratory issues. The company names the laboratory for each report it cites, with the report number and the standard where the report prints them. The filter's label carries the product name, the size and weight fields, the rated airflow and maximum face velocity, the directions for use, the storage and disposal wording and the caution.

All questions

Does a rating describe the lowest efficiency over a particle range or an average?

The two ratings the company publishes are built differently, and their names say so.

MERV is the minimum efficiency reporting value under ANSI/ASHRAE Standard 52.2. It is built from the lowest efficiencies the filter reaches in each particle size range as dust is loaded during the test, not from a single reading on a clean filter. An ISO 16890 class rates a filter against a particle fraction, ePM1, ePM2.5 or ePM10, and the class the filter holds is the one the certificate states. As the company's Validation page puts it, industry standards ASHRAE 52.2 Appendix J and ISO 16890 test electrostatic filters after their temporary charge is removed, showing how they perform without it. Neither rating is a single number describing a whole filter in a building, and neither converts into the other. Certificate No. 15.06.011 covers a ten-pocket bag filter, not a flat panel filter, and Report 6847 is on a 24 × 24 × 30 in. pocket filter; a rating belongs to the construction that was tested. Certificate No. 15.06.011 can be looked up at source in the Eurovent Certita Certification certified product directory.

All questions

Can a minimum efficiency rating be substituted for a clean-air delivery rating?

They measure different things, on different articles.

MERV is the minimum efficiency reporting value under ANSI/ASHRAE Standard 52.2. It is built from the lowest efficiencies the filter reaches in each particle size range as dust is loaded during the test, not from a single reading on a clean filter. An ISO 16890 class rates a filter against a particle fraction, ePM1, ePM2.5 or ePM10, and the class the filter holds is the one the certificate states. A clean air delivery rate is a rating of a portable room air cleaner as a whole appliance, measured under ANSI/AHAM AC-1, the standard for portable household electric room air cleaners. One rates a filter; the other rates an appliance with its own fan, its own housing and its own airflow. This site publishes no clean air delivery rate for its filter. Certificate No. 15.06.011 covers a ten-pocket bag filter, not a flat panel filter, and Report 6847 is on a 24 × 24 × 30 in. pocket filter; a rating belongs to the construction that was tested.

All questions

Does a room-air-cleaner rating apply at the fan speed customers normally use?

This site publishes no clean air delivery rate, so it makes no claim at any fan speed.

A clean air delivery rate is a rating of a portable room air cleaner as a whole appliance, measured under ANSI/AHAM AC-1, the standard for portable household electric room air cleaners. It describes the appliance at the setting used in that test, and that setting is stated with the rating. The company's ratings are filter ratings. MERV is the minimum efficiency reporting value under ANSI/ASHRAE Standard 52.2. It is built from the lowest efficiencies the filter reaches in each particle size range as dust is loaded during the test, not from a single reading on a clean filter. An ISO 16890 class rates a filter against a particle fraction, ePM1, ePM2.5 or ePM10, and the class the filter holds is the one the certificate states. Where a partner builds the filter into an appliance, that appliance and any rating it holds are the partner's.

All questions

Do two quoted ratings use editions of a standard with different classification rules?

The company names the standard and, where the document states it, the edition behind each rating it cites from a numbered report or certificate.

The two air ratings come from two different standards, not from two editions of one: MERV 15A from ANSI/ASHRAE Standard 52.2-2017 with Appendix J, recorded in LMS Technologies, Report 6847, 5 November 2024, and ISO ePM1 70% with an A class energy rating from Eurovent Certita Certification Certificate No. 15.06.011, which certifies a ten-pocket bag filter under ISO 16890. They classify by different rules, and a class under one does not convert into a class under the other. Certificate No. 15.06.011 covers a ten-pocket bag filter, not a flat panel filter, and Report 6847 is on a 24 × 24 × 30 in. pocket filter; a rating belongs to the construction that was tested. The fire reports name their editions on their own scope lines: UL 900, Safety for Air Filter Units, 8th edition dated April 21, 2015, in Intertek reports 105175501SAT-001, 104974202SAT-001 and 105169484SAT-001; and ULC-S111-13, Standard Method of Fire Tests for Air Filter Units, 5th edition December 2013, in Intertek reports 106093268SAT-001 and 106079483SAT-001.

All questions

Are a filter's initial and conditioned results disclosed together?

The ratings the company publishes come from standards that account for the loss of a temporary charge.

As the company's Validation page puts it, industry standards ASHRAE 52.2 Appendix J and ISO 16890 test electrostatic filters after their temporary charge is removed, showing how they perform without it. That is why the MERV rating the company quotes carries the A suffix: it is the rating measured after the conditioning step in Appendix J of that standard. The ISO 16890 class that Eurovent Certita Certification Certificate No. 15.06.011 gives the filter is ISO ePM1 70%, and the certificate record carries the ePM1 average efficiency and the ePM1 minimum efficiency together. Certificate No. 15.06.011 covers a ten-pocket bag filter, not a flat panel filter, and Report 6847 is on a 24 × 24 × 30 in. pocket filter; a rating belongs to the construction that was tested.

All questions

Does a claim of meeting a standard mean all required clauses were assessed?

A report covers the scope it states, and each of the company's reports states its own.

The Intertek reports print a scope of work on the first page, naming the standard, its edition and the article tested: UL 900, Safety for Air Filter Units, 8th edition dated April 21, 2015, testing on a C-POLAR panel filter, and the same form of words for the bag filter and the fan coil filter. The ULC reports do the same for ULC-S111-13, Standard Method of Fire Tests for Air Filter Units, 5th edition December 2013. That line is what was assessed. The company names the laboratory for each report it cites, with the report number and the standard where the report prints them. A standard named in a scope line is the standard the test was run to. It is not a statement that every clause of that standard was assessed on every article the company makes.

All questions

Can an internal test use a standard's name if parts of its method were changed?

A test that changed a standard's method is not a test to that standard, and the company does not present one as the other.

The results the company publishes come from outside laboratories. The company names the laboratory for each report it cites, with the report number and the standard where the report prints them. Those laboratories are LMS Technologies for the air-filtration testing, Intertek Building & Construction for UL 900 and ULC-S111, RST Rail System Testing for DIN 53438-3, and Product Safety Labs for the studies run under Good Laboratory Practice to US EPA Health Effects Test Guidelines. Where a laboratory modified a standard's method, its report says so, and the company repeats it. The Open University of Hong Kong, Test Report IRITS2020007030001R1, 7 June 2021, measured bacterial filtration efficiency on a spunlace nonwoven by a method modified from ASTM F2101:2019, after accelerated ageing to ASTM F1980-16 equivalent to five years at room temperature. A reader can see who ran each test and under what, and can ask for the report.

All questions

Is the standard being cited for a property it was designed to evaluate?

Each standard the company names is cited for the property it was written to evaluate, and for nothing else.

UL 900, Safety for Air Filter Units, and ULC-S111-13, Standard Method of Fire Tests for Air Filter Units, are fire tests on air filter units; they say nothing about what a filter captures from the air and nothing about microorganisms. DIN 53438-3 is a fire test, and the reports that name it were run on filter media. ANSI/ASHRAE Standard 52.2 and ISO 16890 measure what a filter captures from the air. Textile Testing Institute – Brno (TZÚ), Test Report AZL 26/0757-02, 3 July 2026, a laboratory accredited to ISO/IEC 17025, tested a MERV 15A filter medium under ISO 20743 and ISO 18184. An activity value is a difference against an untreated control fabric. It is not a percentage destroyed and not an airborne result. The Viruses page shows airborne virus at 1.3 m/s airflow, NanoFlashing™ beside a control, and states: “NanoFlashing™ captures the virus, and destroys it.” The Mold page shows airborne mold spores at 1.6 m/s airflow, NanoFlashing™ beside a control, and states: “NanoFlashing™ captures the mold, and destroys it.” The Mold page also states that researchers at Massachusetts General Hospital and Harvard Medical School, in a study with funding from the U.S. National Institutes of Health, tested NanoFlashing™ with more than 100 million live, dry spores driven in by fast-moving air. OEKO-TEX® STANDARD 100 is, in the scheme's own words, a testing and certification system for textiles tested for harmful substances; it is not a test of what a filter captures. The studies run under Good Laboratory Practice to US EPA Health Effects Test Guidelines are health effects studies, not performance tests. A standard cited outside its own subject proves nothing, which is why each of these is named with the report it comes from. Both numbers can be checked at source: certificate 17.0.25812 in OEKO-TEX’s public label check, and Certificate No. 15.06.011 in the Eurovent Certita Certification certified product directory.

All questions

Does the certification programme require complaints to be reported to its issuer?

A complaint about a certified product belongs with the holder of the certificate and with the issuer, and both are named.

The issuer sets those conditions in its scheme rules, and they bind the holder of the certificate. The certificates the company names are held by the manufacturer that makes the filters. They are OEKO-TEX® STANDARD 100 certificate 17.0.25812, issued by OEKO-TEX Service GmbH, and Eurovent Certita Certification Certificate No. 15.06.011, and each issuer’s own record names the holder of its certificate.

All questions

Is the supplier entitled to use a certification mark after the licence fee lapses?

A certification mark may be used only while the certificate is in force, and only by its holder, under the issuer's rules.

The company names certificates by their issuer and their number, and it does not present a certification mark as its own. The certificates the company names are held by the manufacturer that makes the filters, not by C-POLAR: OEKO-TEX® STANDARD 100 certificate 17.0.25812, issued by OEKO-TEX Service GmbH, and Eurovent Certita Certification Certificate No. 15.06.011. Each issuer's own record names the holder of its certificate. Whether a certificate is in force is shown by the issuer's own record: OEKO-TEX publishes a public label check, and Eurovent Certita Certification publishes a certified product directory of the products certified under its programmes.

All questions

Can a certification renewal rely on old test samples after a material change?

A certificate covers the product that was tested, and a changed product is a different product for that purpose.

The issuer sets those conditions in its scheme rules, and they bind the holder of the certificate. The certificates the company names are held by the manufacturer that makes the filters. The company does not operate those schemes, does not set their thresholds, and does not publish a second set of rules alongside them. What a renewal needs is therefore the issuer's decision, taken against its own rules. Both numbers can be checked at source: certificate 17.0.25812 in OEKO-TEX’s public label check, and Certificate No. 15.06.011 in the Eurovent Certita Certification certified product directory.

All questions

Does a certificate's scope distinguish a material roll from a complete filtration assembly?

Yes, and the company's own records show both kinds side by side.

The DIN 53438-3 fire tests, RST Rail System Testing reports P60-22-0003 and P60-24-0297, were run on filter media. The UL 900 and ULC-S111 fire tests were run on complete filter units, and each report names which one: Intertek Building & Construction report 105175501SAT-001 on a panel filter, 104974202SAT-001 on a bag filter, 105169484SAT-001 on a fan coil filter, 106093268SAT-001 on a pleated filter and 106079483SAT-001 on a pocket filter. Each document states its own scope, and that is the limit of what it covers. A result on media is not a result on an assembly, and a result on one construction is not a result on another.

All questions

The OEKO-TEX certificate for the filter media mentions biologically active products. Is NanoFlashing™ one of them?

C-POLAR describes NanoFlashing™ as a physical property, not a substance, and the scope text is OEKO-TEX’s description of the certificate holder’s whole range of filter media.

The Validation page states: “NanoFlashing™ is certified to OEKO-TEX® Standard 100, Product Class II, the class for products in direct contact with skin.” OEKO-TEX® STANDARD 100 Certificate 17.0.25812 is held by Volz Luftfilter GmbH & Co. KG, one of the manufacturing partners, and it covers a range of Volz filter media, including media sold under other names. Its scope states that the range is “partly finished with biologically active prouducts accepted by OEKO-TEX®” [sic], and it does not say which media in the range that part is. NanoFlashing™ is a permanent positive polarity engineered into filter media itself. It is a physical property of the filter. A charge is a physical property. It is not a substance or a mixture of substances. The company's Statement of Regulatory Status for the NanoFlashing™ Air Filter states: “The filter has not been treated with a biocidal product and does not incorporate one”.

All questions

Does installing NanoFlashing™ qualify a building for LEED, WELL or another green-building certification credit?

C-POLAR publishes no statement that NanoFlashing™ earns a LEED, WELL or other green-building certification credit.

The company sets out the filter's physical description in its Statement of Classification, and the Validation page names the test records. NanoFlashing™ is a permanent positive polarity engineered into filter media itself. It is a physical property of the filter. For its air-filtration statements, the Validation page names LMS Technologies, Report 9904; LMS Technologies, Report 6847; and Eurovent Certita Certification, Certificate No. 15.06.011. A question about a particular certification programme can be sent to [email protected].

All questions

Does the Eurovent ‘A’ energy class shown on the Validation page mean the filter qualifies for a US ENERGY STAR rating or a tax credit or utility rebate?

No. The A on the Validation page is the energy efficiency class on a Eurovent certificate, and the company publishes no ENERGY STAR listing, tax credit or utility rebate for the filter.

The Validation page names Eurovent Certita Certification, Certificate No. 15.06.011, and states that Eurovent certifies the filter with an A class energy rating. The certificate gives that class as an energy efficiency class based on ISO 16890, for the model PROsyntex PLUS-PM1/70-635-10, with VOLZ LUFTFILTER GmbH & Co. KG as the participant. A certificate belongs to the model it names. A question about a particular rebate or credit programme can be sent to [email protected].

All questions

What does the UL 900, ULC-S111, DIN 53438 and RoHS compliance named on the Validation page actually mean?

UL 900, ULC-S111 and DIN 53438 are fire tests, EU RoHS is a European Union directive, and the Validation page lists the test reports behind each.

The Validation page states: “NanoFlashing™ complies with UL 900, ULC-S111, DIN 53438 and EU RoHS.” UL 900 is Safety for Air Filter Units: Intertek Building & Construction, Report 104974202SAT-001, 23 February 2022, tested a bag filter; Report 105169484SAT-001, 18 August 2022, a fan coil filter; and Report 105175501SAT-001, 29 August 2022, a panel filter, each under UL 900. ULC-S111 is the Standard Method of Fire Tests for Air Filter Units: Intertek Building & Construction, Report 106093268SAT-001, 28 January 2025, tested a pleated filter, and Report 106079483SAT-001, 15 January 2025, a pocket filter, each under ULC-S111-13. DIN 53438-3 tests how a combustible material behaves when a burner flame is applied to its surface: RST Rail System Testing, Report P60-22-0003, 18 January 2022, and Report P60-24-0297, 16 May 2024, tested filter media under it. EU RoHS is Directive 2011/65/EU: the record the page names for it is Intertek, Report HKGT05289390, 14 January 2022. The Product Safety Labs studies on the same list, Studies 65321, 65322, 65323 and 65324, are health-effects studies under US EPA Health Effects Test Guidelines, not fire or RoHS records. Each report describes what that test found on the article it names.
